overcharged battery in NH skid steer now NO start?

[mrbb]

OK, I have a LX 865 skid steer, installed a new battery before winter, and added a battery tender(Schumacher tender via a 2 prong SAE plug)
tender was showing full charge two weeks ago, (Last time I looked)
today when to use skid steer, disconnected charger as alweays
turn key and get super high pitch buzzer alarm sound, and ZERO lights on display, like dead display and alrm just going nuts
plug tender back in, just to see status of battery as has level meter on it
and it is DEAD, ZERO lights on tender,
THINKING tender some how went bad?
pull side panel off to access battery and test battery with volt meter, and it reads 15.35 volts, WAY over charged
so now think charger over charged and maybe ruined something, but WHAT

any suggestions here?
dead in water at this point, and NOT the greatest MR fix it, so, any and all help appreciated!

Take the battery out and add distilled water to your battery up to the level of the bottom of the tubes. You boiled the water off with the battery tender, maybe even a shorted cell caused it? 15V resting means the acid is overconcentrated, but that doesn't mean the battery has more power because the level is too low to put out the amps it should.

I'd pull it out, fill the water, charge it, and test it on another machine, then go back and see what happens. Or try a good battery.

OK thanks, right now getting to battery is a big problem, machine is parked in a corner up against a wall, and NOT much room to work, side covers will NOT come out/off to make room, CRAPPY design for where battery is, cannot open rear down more than about 1/3 of the way too
unbolted the one side shied base, JUST to get to terminals, but NO clue how I would get to hold onto battery to even try and lift it out of place, I have health issue's that limit many things I can do
way its set up, is to lift boom up and lock it, then pull panels and remove battery
so without starting machine, its no easy task
tried to drag skid steer some with my 2500,m RAM Cummin's
but NO go there truck just spins . in a building with a low ceiling too, so, not helping

BUT even if battery was swapped out with a new one
I am still having issue's with the alarm going off, this worries me more than a battery being down on fluid
a sI gather something must have tripped a fuse or cooked something to cause it to not allow display to light and throw alarm on??
fuses in IN AB fuse block all good, one's on behind motor on fire wall like, I cannot REACH to check
in my service manual(not owners manual) it DOESN"T say what fuse is for what either
IF I could ever reach one to pull and check, like to try and limit what one's I plull if I can due to they too, are designed to be checked with BOOM up, something I cannot do at all !

SO, any thoughts on why this alarm is going off, what fuse to what should I be looking at??

 

[Delmer]

No idea on the alarm. I'd put a volt meter wherever you can reach and see what the voltage does when you turn it on and the alarm goes off. Figure that out first. Also, if the voltage stays high, check the voltmeter against a good battery.

If you can reach the top of the battery, you might be able to pry the covers off, or get a hose on the vent and fill it with distilled water that way.

Let us know what the battery voltage does sitting and with the machine on. Or maybe somebody else has seen this before in a NH.

ok, little update
when I FIRST took reading off battery it was about 20 minutes after I un plugged the BAD tender, and it read 15.35 volts(GOOD meter)
I waited about an hr and took a reading again, and its NOW reading 13.35 volts
so it came down on its own(BUT this machine has a drain some where, ,when I got it and old owner just added a quick dis connect at battery
I left that ON< knowing it would drain some, and seems to have done that!

I still CANNOT start the machine, it will do NOTHING when I turn the key, minus that alarm buzzer going off and says on as long as key is in run /to start position or to the left, alarm sound every way you turn key
it stays on if I put machine in service mode too, , and still NOTHING when you turn the key, minus alarm sounding off!
NO dash lighting up, NOTHING
so, s of right now I am dead here , I checked fuses inside cab, and all good, fuse box on motor side, I cannot reach to pull and inspect fuses
so, trying to figure out how to do that
and woudl LOVE to find out what fuse is for what, as NO where in service manual or owners manual does it show what fuses are for what?
as being so darn hard to get to, rather NOT have to pull all if possible and just pull higher odds one's of possible problem!

SO if anyone know's what fuses are for what and what one's I shoudl check first here, please let me know

 

[mrbb]

these are fuses on back side of seat fire wall(motor bay )

any clue what one is for what??

 

[hosspuller]

Machine is on a concrete floor ? is so... that's good. You'll have to do it the Egyptian Pharaoh's way. Jack the machine up, put boards under it with sections of steel pipe as rollers. Your Cummins or a bunch of Israelis will pull it out for working room.

Or figure out how to release the wheel motors hydraulically

 

[mrbb]

thanks for suggestion, but I don;t have any steel rollers, all I have maybe would be PVC, and don;'t have much if it either, not sure if it would hold, have used it to move a few sheds, but there not as heavy as this thing!

I do have a HD floor jack on wheels, maybe could lift one end and the try dragging with truck, might get it far enough to at least remove covers?
still hoping someoen can tell me what fuses are for what ?? so, anyone know, or have advice on where I might find a chart showing what each fuse if for?

 

[62oliver]

Can you boost it with your truck to get it moved to where you can get at it? Sounds like even a couple of feet would help.

 

[mrbb]

I think maybe I am not being clear
the battery is NOT the problem
the problem is again
the tender overcharged the system on skid steer, and in doing so something got damaged
I lost all dash lights, and when I TRY to start it, all I get is a very HIGH pitched alarm.buzzer
NOTHING else happens
if I put a NEW battery in, it doesn't change things here, something electrical is damaged some where from being overcharged
and I have NO clue what
the fuses I could check in cab, were all good, and cannot reach the fuses in the motor bay area(in picture above taken with a ZOOM on camera)
so, if I can SOME how maybe get to a fuse there, I woudl like to try and limit HOW many I need to pull to check due to how hard they are to reach, IF possible at all to reach!

and if NOT a fuse, then what got damaged and is causing the alarm to go off/ NO lights on dash to light up, and NOT allowing to start machine
and again, even in service mode, it still will NOT do anything!
battery is holding steady at 13 volts, so battery actually seems OK, as far as on a meter reading goes and battery is only 6 months old or so!

 

[Delmer]

You're making yourself perfectly clear. Here's my suggestion.

1. Decide if you want help, or if you know it all already.
2. What happened to your former thread on the starting problem?
3.What's the voltage with the key on and the alarm sounding? Voltage when the key is at start?
4.What voltage do you get with that meter with a known good battery?

Maybe you've done these and know what you're talking about, but you haven't stated that, and it doesn't sound like you know what you're talking about. So help us out a little.

MrBB... You state "in my service manual(not owners manual) it DOESN"T say what fuse is for "...
That's hard to believe...maybe look again, VERY carefully, & do you have an Owner's Manual?? It should certainly show what fuses are for. If no manual, do a google search for NH LX 865 manuals & maybe something will pop up.

Also, it's possible you have wire damage somewhere due to mouse chewing.

 

[mrbb]

I have looked several times and I cannot find ANY chart that shows what the fuses are for, it goes into detail telling what color wires run to what, but not what each fuse
and IO do have BOTH service manual and owners manual
the fuse box section is 3-125 in manual, and is about 6 pages long on fuse box, and NO where dies it again have a chart showing what each fuse if for, very frustrating
it has a chart showing fuse box, and all relays and it has numbers arrows for ALL relay'
s stating what each is for, but when you get to fuse box, it just says. uses standard fuse box? and an arrow pointing to the whole box, rather than any info on what each fuse is for
MAYBE I am missing something, but I have looked and cannot find ANY thing that shows , what each fuse if for
and I have a hard copy printed coy of both manuals
if anyone can find what they are for, I would be very thankful as I seem to not be able to in the manual! and I cannot get close enough to it to use wire colors to determine that way!

Found this in the two minutes I was sitting on the toilet. https://www.justanswer.com/construc...i-new-holland-lx865-turbo-will-not-start.html

 

[heymccall]

Thinking (pushing) harder here...who cares what each fuse does (at least initially). Just test them all. They're ATC type...just walk a test light down each one.

 

[mrbb]

thanks
but to be clear, the first pic/ you show is for the IN CAB fuse block, and that is stating what each fuse if for, and I have gone thru all them and they are good!

the second one, again, is like what I have, it shows what each relay is for, but leaves the two fuse blocks , as just, #5 and # there as standard fuse block and optional fuse block, DOESN"T list what each fuse if for again

and the problem I have right now is I cannot REACH the fuse block in motor bay, my arms are a about 2 ft too short, and my health issue's are limiting me from getting more creative to get to them
So I am trying to LIMIT the guessing game and only having to pull and check fuses in there as there so hard for me to get to them, and as of now don't have anyone to help me, l;ve rather remote and help isn't about!

so again, there is NO chart stating what each fuse if for in the Motor bay, JUST the IN cab from MY understanding of things shown *(and what I have seen)

 

[mrbb]

I did manage to get the fuses cleaner(sprayed them with electrical contact cleaner, as they wee dusty, and looks to me like maybe the top 2 on the right side might be bad? or second one down, seems to have a broken wire inside it!
just GUESSING still cannot reach them however
called a buddy that works on equipment to come help m,e, so, waiting on him to get back to me
will update once figured out' but all this was caused by a BAD battery tender that over charged things?

 

[hosspuller]

Actually... looks to me like the top 25 is blown. And the second from top 20 is blown too.

But only way to tell is to pull and test.

My suggestion to pull the machine clear to work on it, would save you a lot of trouble. A couple of 3/4 pipe pieces from a salvage yard wouldn't cost much. PVC won't hold the weight. That's assuming you can jack the machine up.

 

[heymccall]

The two pics I posted appear to be for the same fuse panels. Are you saying that there are FOUR 4fuse panels?
As for testing, even though the confines are tighter, you can end probe that style of fuse.

 

[mrbb]

the IN cab fuse , can have two fuse blocks, and mine ONLY has one
the IN motor area again, can have 1 or two fuse blocks and mine has TWO there
they are different fuse blocks and pic's you posted are of different blocks, , the IN cab one, and then the in motor area one

and I get you can test , but I cannot reach fuse blocks to even PULL fuses and if I DO get them out using maybe some extra long needle nose pliers, I am NOT sure if I can get them back in be hanging upside down in a HARD position for me, with my messed up back and hands (fingers don't work very well)
